Bell Inequalities for Position Measurements [PDF]
Physical Review A, 2003 Bell inequalities for position measurements are derived using the bits of the binary expansion of position-measurement results. Violations of these inequalities are obtained from the output state of the Non-degenerate Optical Parametric Amplifier.Comment:

Eddy Current Position Measurement in Harsh Environments: A Temperature Compensation and Calibration Approach [PDF]
SensorsEddy current displacement sensors (ECDSs) are widely used for the noncontact position measurement of small displacements (lift-offs). Challenges arise with larger displacements as the sensitivity of the ECDSs decreases.

Multilateration of the Local Position Measurement [PDF]
2016 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2016 The Local Position Measurement system (LPM) is one of the most precise systems for 3D position estimation. It is able to operate in- and outdoor and updates at a rate up to 1000 measurements per second. Previous scientific publications focused on the time of arrival equation (TOA) provided by the LPM and filtering after the numerical position ...
